#NiCl_3# is a strong electrolyte. How do you determine the concentration of each of the individual ions in a 0.400 M #NiCl_3# solution?

Answer:

I think you mean #NiCl_2#.

Explanation:

In aqueous solution, nickel chloride gives a beautiful green solution, which we would represent as #[Ni(OH_2)_6]^(2+)# or simply as #Ni^(2+)(aq)#. Two (aquated) chloride counterions, #Cl^(-)(aq)#, are along for the ride.

The concentration of the hexaqua complex is (clearly) #0.400*mol*L^-1#. The concentration of the chloride counterions is #0.800*mol*L^-1#.
